I saw this on a bottle of body wash.

Problem:
A possessive apostrophe is missing.

Explanation:
The noun “nature” is rarely pluralized, given its dominant definitions.

One definition for which pluralization makes sense is the fundamental disposition or temperament of a person.

However, that particular definition would be inconsistent with body wash.

Instead, the “Natures Family” brand alludes to the botanical elements in the body wash.

Given that no trademark symbol appeared adjacent to the “Natures Family” brand, which would have implied that the lack of punctuation was intentional, I have to conclude that the omission of a possessive apostrophe was an error.

Solution:
“Nature’s Family”
